Actually, it might have worked better if the PG had stayed down while running
cephfs-data-scan, as it could only then get file structure from metadata pool
and not touch each file/link in data pool?
This would at least properly have given the list of files in (only) the
affected PG?

Hi Felix,
The last time we looked at Samba was with Nautilus, accessed via a
Scientific Linux 7.4 server and client. We didn't use clustering, or the
VFS module.
Performance was disappointing, though our use case is small numbers of
clients, with large Scientific data sets.

Hi,
I have recently been scanning the files in a PG with "cephfs-data-scan pg_files
...".
Although, after a long time the scan was still running and the list of files
consumed 44 GB, I stopped it, as something obviously was very wrong.
It turns out some users had symlinks that looped and even
